FOR RING-SPINNING MACHINES.

Iat ented ma 1, 1906.

Application-filed May 3,1906. Saris-1N0. 258,640- A This invention relates to that class of spin:

ning and twisting frames in which a vertical movement in relation to the spindles is imparted to the ring-rail and the invention articularly relates to improvements wherehy both the thread-guides and the separators follow the movements of the ring-rail. I

The object of this invention is to provide a simple and cheap separator and one which will prevent any possibility of the yarn balloomng, even wit a very long traverse and high speed. v A further object of the invention is to provide a structure in which the number of parts used is reduced to the minimum and having no partswhich are liable to break or get out of order, as is frequently the case with the blade type of separator, and atthe same time furnishing all or more of the conven-. iences than are obtained with the blade-separator.

A further object of the invention is to provide a stucture of separator which {nay be used with and operated by the mechanism tion. view of the for raising and lowering the threadguides, as shown in my Patent No. 624,148, granted May 2, 1899.

To these ends my invention consists in the construction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents a perspective view of so much of a spinning-frame as is necessary to illustrate this invention, the present improved attachment being shown as connected therewith. Fig. 2 represents a detail side elevation of my improved attachment in its relationship to the rin -rail, the latter being shown in seci ig. 3 represents an enlarged detail u per end of one of the threadeye-lifting rods and the parts carried thereby, this ortion of the attachment being similar to-that in my patent above mentioned. Fig. 4 represents an enlarged detail view of the bracket, partly in section, for the separators and separator-rod.

i 1 Similarreference charactersindicate similar parts throughout the several views.

The delivering-rolls 10, roller-beam 1 1, ringrail 12, spindle rail 13, spindles 14, and lower or guide rail 15 are such as in an ordinar type of spinning-frame. One of the liftingrods for the ring-rail is shown at 16, having a shoe or foot 17 restin upon a roller 20, mounted on a pin or stu 19, projecting from the hfter-arm 18, the latter being actuated by these portions of the present attachment being similar to those in my above-mentioned patent. Y

A bracket 23 is shown as secured to the under side of and rising from the lower or guide rail 15, said bracket having ides 24 for the thread-eye-lifting rod 25. fi will be understood, of course, that any number of such lifting-rods as may be necessary to roperly support the thread-eyes and their rod are employed in the spinning-frame. The upper end of each rod 25 is provided with a slotted head 26 for the ide-wire rod 27, extending from end to en of the machine above the ring-rail. Secured to the said rod 27 and located in the slot of each head 26 is a cam 28, having two shoulders a and b adapted to alternately engage the bottom of the slot in the head 26, according to the direction in which the rod 27 may be turned. These shoulders (I. and b are so, spaced as to permit of a rotati'on of the rod. 27 slightly more than onefourth of a circle. At suitable points, according to the space between the spindles, the rod 27 is perforated toreceive the guide-Wire studs 29, each of said studs being jointed to provide an outer arm 30, which may be turned upward and backward, each of said arms being provided with a thread-eye 31. This structure is substantially the same as shown in my patent referred to and produces means whereby the rod'27 may be rotated to throw all of the eyes back and hold them in position for dofiing and may be returned, so that the guide-wire studs will be in a horizontal position for spinning, and of course either of the arms 30 may be turned upward to enable anindividual bobbin to be removed for piecing up ends, &c. The lower end of each rod 25 is provided with a foot 32, resting on a pin 33, projecting from the lifter-arm 18, the atter bein provided with an elongated slot 34, throug which the pin 33 extends. .A nut 35 secures the pin 33 in-its adjusted posi- ICC s the cross-shaft 21, supported by a bracket 22 tion in the slot 34, said slot bein of a length to permit of a wide range of adjustment to vary the amount of vertical movement that will be imparted to the thread-eyes. Each rod 25 is provided with a collar 36, which may be adjustably mounted on said rod. A bracket 37, having a sleeve portion 38 loose 011 the rod 25, is engaged by the collar 36, so as to be lifted when the rod 25 moves upwardly. The bracket 37 is provided with a slotted head 39, and two or more of such brackets and heads support the horizontal separator-rod 40, which extends withthe ring-rail from end to end of the machine. Each slotted head is formed with a transverse hole which forms a bearing for said rod to permit the latter to be turned thereon.

The separators 41 consist each of a wire bent so as to form as much of a circle as possible, while leaving suilicient space in the front to allow of the separators being thrown back out of the way when doifing. The diameter of the upper circle formed by the separator and the width of the opening will depend on the size of the ring that is used. and the size of the full bobbin. The Wire forming the separator is bent so as to provide two wires on each side of the ring or bobbin, said two wires being any required distance apart to suit the Work to 'be done. The outer or front ends of the doubled wiresare bent outward or fiared from a true circle, so as to avoid any liability of the thread being thrown over or around the ends of the separator when a very light traveler and long traverse is used to spin soft twisted yarns at high speeds. The ends of the wire extend back and form shanks or studs, which pass through suitable holes in the rod 40. As indicated in the drawings, the rear ends or shanks of the Wire are provided with nuts 42 to retain them in their holes or bearings in said rod.

Secured to the rod 40 by means of a setscrew 44 and located in the slot of each head 39 is a cam-stop 43, having stop-shoulders c and d, which are adapted to alternately engage the bottom of the slot in the head, ac-

cording to the direction in which the separators may be turned. These stop-shoulders are so spaced as to permit of a rotation of the rod and the separators slightly more than one-fourth of a circle, so that when spinnin they will rest in a substantially horizonta position, and when thrown back they will pass beyond a vertical position and remain in that position until again thrown forward.

As has been stated, each bracket 37 is loose upon the rod 25, and the lowermost positionwhich a screw 47 passes into, the vertical member 46 of the bracket. Preferably the adjacent surfaces of the two members of the bracket are corrugated, so that the operative portion of said bracket may be lengthened or shortened, as required, and the adjustment retained without. any possible chance of slipp A s will be readily understood, the separators rise and fall with the thread-eyes, excepting at such times as the traverse of the ring rail causes the vertical members 46 of the adjustable brackets, which are carried by the ring-rail, to engage the under surface of the projecting portions of the sliding brackets 37 and cause the latter to slide on the rods 25, whereby the separators will partake of the movements of the ring-rail.
